I have a 1999 Deville and recently the rear end of my car raised noticeably (possibly on a recent golf trip with three other guys along with equipment)and it looks like I'm going downhill all the time.Can anyone on this forum explain how to get my car back level again?thanks in advance,Bob

1 have a 2000 dts and have the same problem.but i was wondering if the front end has dropped instead of the rear rasing up.

You have leveler arms on the rear axle if one of the arms came off it will sense the car is low and raise the rear. You can look at the rear axle and see the little box with the arm that hangs down on my car it is on the drivers side.As mentioned above post there is a fuse for the exhaust for the air compressor that allows the excess air to bleed off, everytime you start your car the compressor comes on and runs for a few seconds, the exhaust valve relieves the air not needed.If that doesn't fix your problem, take off one of the rear tires and take the hose off the shock the air will come out and equalize pressure in both shocks. If your car starts to raise everytime you start it after that, something is wrong with your exhaust valve on your compressor and it will be needed to be fixed.Or like mine I just pulled the ELC (elestronic level control)fuse out so the compressor never cycles and the shocks don't get pumped up very start, but I usually drive with only me and sometimes with a passenger so my rear end never gets weighted down enough the shocks have to level the car
